Current models of outpatient childhood obesity treatment focus on the child's health habits, with limited efficacy. In part, this may be because childhood obesity is highly sensitive to parental lifestyle habits, who are often not a direct target of child obesity interventions. This study aims to target weight loss among overweight parents of 2-16 year old children with obesity enrolled in the Duke Healthy Lifestyles Program (HL) in order to augment child body mass index reduction. The intervention, " Families on Track" is a digital health intervention platform using the Interactive Obesity Treatment Approach (iOTA).
